The rose, often referred to as the "queen of flowers", is unfortunately quite susceptible to various fungal diseases. However, this can be prevented by choosing a less sensitive variety and taking the right precautions.
Brown leaves on the rose can indicate a fungal disease
Various fungal diseases cause brown leaves
If the rose petals develop large, black-brown spots, this is often caused by black spot caused by the fungus Diplocarpon rosae - one of the most common rose diseases. If, on the other hand, the spots are initially orange and only later turn brownish, then the rose rust has attacked your roses.
Treat infested roses properly
Basically, affected areas should be removed as quickly as possible with rose scissors. After that, however, the infected leaves and shoots do not belong in the compost, but in the household waste. In severe cases, a chemical treatment can also be useful, since the roses are otherwise completely leafless by midsummer.
tips
Prevention is better than cure: Always water roses from below, the leaves must not be wetted and must be able to dry quickly. That is why an airy location is so important! In addition to species-appropriate care, the right soil and a sunny but not too warm place are also relevant for rose health.
